In order to provide a simple structure and to reduce the overall height, the feed container is designed to constitute a lock chamber, which is provided with a shut-off valve for controlling the inlet port of the feed container and with a plurality of shut-off valves for controlling respective outlet ports connected to the charging ducts.
Description
The present invention relates to the loading installation of shaft furnace of roasting carbonate containing mineral calcining matter in two shafts at least, this charging apparatus comprises a shared charge cask, and this charge cask respectively is connected with shaft by a feed pipe.
In the equipment of existing this type (AT-PS377078), at shared charge cask with alternately adorn between the shaft furnace shaft of calcining matter conveying pipeline is housed, calcining matter is transported in one of them shaft from charge cask by these conveying pipelines.Because in this charge cask, meausring apparatus is housed, so it can guarantee to feed in raw material by the calcining matter quantity of predesignating, the charging apparatus that all has a charge cask with each shaft is compared, the advantage of this equipment is: all available easy method of all shafts fed in raw material with identical inventory, and can be because of do not cause the difference of metering according to each shaft meausring apparatus separately.In addition, construction expenditure also correspondingly will reduce.Though such advantage is arranged, but also has shortcoming: in order behind the shaft hermetically closing, to carry, pressure must be housed between material container and the single shaft slip the ore deposit groove in shared adding, this has just increased necessary building height, and pressure slide ore deposit groove may be made up of the clock-type closer that a flashboard is installed and install on each shaft below flashboard.Like this, after flashboard cuts out, before the clock-type closer is opened, for giving a shaft charging, must be added in the calcining matter of the weighing already in the charge cask, store up when the gate opening in the tube chamber between flashboard and the clock-type closer by affiliated carrier pipe.Because calcining matter is at the aliquation on the clock of closing of clock-type closer, sealing surface is loaded by calcining matter, and this will cause bad stand under load situation.
The charging apparatus that the objective of the invention is to avoid these shortcomings and improve the above-mentioned type: under the situation of simple assurance shaft hermetically closing, can reduce the building height of charging apparatus necessity.
The present invention's mode of achieving the above object is: just as ore passing groove chamber, this ore passing groove chamber respectively is equipped with one and slips ore deposit groove lock on the import of charge cask and the connector at feed pipe with charge cask.
Because charge cask itself becomes ore passing groove chamber, so there is no need an ore passing groove chamber to charge cask to be installed again.Therefore, the building height of charging apparatus just can reduce the height of habitual ore passing groove chamber, as ore passing groove chamber building height is reduced with charge cask, and makes designs simplification, because each shaft no longer needs to install separately ore passing groove chamber.Because, for the calcining matter that will be contained in the weighing already in the charge cask is packed in the shaft,, so just can material be packed in the shaft by feed pipe as long as it is just passable to open the slide ore deposit groove lock of feed pipe connector, this just brings simplified control and advantage.
Other improvement of the present invention is: if slide ore deposit groove lock respectively is equipped with a flashboard in the import or the connector port of export, this flashboard in off position down, overlap with the flanged ring that has the import that seals collar or connector, like this, just can enough simple methods avoid sealing surface to be subjected to the bump of calcining matter, sealing surface be positioned at the outside of flanged ring, and flanged ring faces flashboard, thereby avoided calcining matter to enter sealing surface, so can there be higher service life.
In order to cause the pressure balance of opening flashboard with straightforward procedure, last flashboard can be opened by rocking arm, and rocking arm can move a certain distance with respect to flashboard act on flashboard on its swaying direction before, and handles the equilibrated valve that is arranged in the flashboard.Because rocking arm flashboard relatively turns an angle, be placed in the interior equilibrated valve of flashboard so can utilize consequent rocking arm idle stroke to operate.If rocking arm turns to unlatching from the closed position, so, pass by idle stroke and affact on the flashboard at rocking arm, and before opening this flashboard, just at first by rocking arm opening pressure balanced valve.So, before the ore deposit groove lock that slips is opened, but only need just imperative operation equilibrated valve of very little operating physical force.
In conjunction with the accompanying drawings, describe one embodiment of the present of invention in detail.
Fig. 1 represents the front view according to the charging apparatus of twin furnace shaft furnace of the present invention.
Fig. 2 is illustrated in the magnification ratio sketch of charge cask import department slide ore deposit groove lock.
Fig. 3 illustrates the profile of the slide ore deposit groove lock at feed pipe connector place with same magnification ratio.
According to Fig. 1, two shafts 1 of twin furnace shaft furnace and 2 charging apparatus mainly comprise a charge cask 3.Charge cask 3 is connected with 2 with shaft 1 with 5 by two feed pipes 4.Thereby the roasting material that is contained in already in the charge cask 3 of weighing can alternately be admitted to shaft 1 and 2.The transporter of for the sake of clarity and not drawing is used for to charge cask 3 chargings, and transporter is put into calcining matter in the charge cask by import 6.
Different with known charging apparatus is that charge cask 3 constitutes ore passing groove chamber, and slide ore deposit groove lock 8 is housed at connector 7 places of charge cask import 6 places and feed pipe 4 and 5.According to the embodiment of Fig. 2 and 3, the ore deposit groove lock that slips respectively comprises a flashboard 9, and it is fixed on the rocking arm 10.As shown in Figure 1, rocking arm 10 is contained on the control lever shaft 11, and control lever shaft 11 is rotated by an adjusting rod 13 by a pressurized strut 12.Here, be to adopt a kind of like this structure: have the rocking arm 10 of a bracket pins 14 and be connected with the elongated hole 15 of carrier base 16 on flashboard 9.Like this, when rocking arm 10 was regulated by control lever shaft 11 rotations, before flashboard 9 was unlocked, rocking arm 10 was walked an idle stroke according to the size in the gap that elongated hole 15 provides.This idle stroke is used to handle equilibrated valve 17, and equilibrated valve is contained in the flashboard 9, and can open by the prolongation lever 18 of rocking arm 10.Just as shown in Figures 2 and 3, for achieving the above object, the valve body of equilibrated valve is connected with the prolongation lever 18 of rocking arm 10.
For example, if the slide ore deposit groove lock 8 on the connector 7 of unlatching feed pipe 5 so, just drives rocking arm 10 by affiliated pressurized strut 12, adjustment (adjusting) lever 13 and control lever shaft 11.At this moment, in the phase I that rocking arm 10 rotates, equilibrated valve 17 is opened earlier, like this, has just set up pressure balance between charge cask 3 and shaft 2.Then, in the second stage that rocking arm 10 rotates, flashboard 9 just is opened.Dot the enable possition among Fig. 3.After flashboard was opened, calcining matter can unhinderedly arrive shaft 2 from charge cask 3 by feed pipe 5.At this moment, must close charge cask 3 imports 6 places and the slide ore deposit groove lock that is connected the feed pipe 4 connector places on the shaft 1, this needs explanation in detail.When closing flashboard 9, motion process carries out with relative direction.After flashboard 9 cut out, equilibrated valve 17 cut out by prolonging lever 18.So just guaranteed the shaft hermetically closing again.
In order to guarantee to cause particularly advantageous sealing situation slipping groove lock zone, ore deposit, have a sealing collar 19 at the flashboard 9 of the port of export device of each import 6 or connector 7, the flanged ring 20 that has the flashboard 9 that seal collar 19 and import 6 or connector 7 is overlapping.Because flanged ring 20 protrudes in the flashboard 9, and by sealing collar 19 cross-lappings of flashboard 9, so the sealing ring 21 of flashboard 9 does not contact with calcining matter, this is to playing a part useful its service life.
As shown in Figure 1, shaft 1 alternately is connected with an exhaust piping 24 with a fresh air pipe 23 by a changement 22 with 2, so the shaft of gaseous fuel from being connected with fresh air pipe 23, for example shaft 1, arrives another shaft 2 by an overflow pipe of not drawing.Before gaseous fuel is discharged by exhaust piping 24 from shaft 2, can be there with reflux type preheating and baking thing.After changement 22 commutations, fuel and fresh air are admitted in the shaft 2, and shaft 2 is in advance once with the heating by the exhaust gases mistake of adverse current form quilt from another shaft 1, and gaseous fuel flows into shaft 2 with the following current form together with calcining matter.At this moment, just can be with reflux type preheating and baking thing in another shaft 1.The charging of the calcining matter of two shafts can be selectively during counter-current operation or following current operating period carry out.
